vygon.com website review

28 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

About 150 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

About 53 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

The page has 1,605 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

2 third-party services load with your homepage (Google Tag Manager and Matomo), adding 165 KiB and 165 ms of main-thread time.

4 images could be 156 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

4 long tasks block the main thread while loading, the longest for 109 ms. During a long task the page ignores taps.

36 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

1 file is served with short cache lifetimes, so returning visitors download them again (4 KiB).

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 6.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Bébé nutrisafe2”.

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.5 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 6.4 s. Good is under 3.8 s.

Visually, the page fills in at 4.7 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 149 ms to 156 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.5 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

noe-en-viv-10-copie.webp is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

3 images are downloaded at several times the size a phone draws them, for example vyneodays.png at 576 px wide, shown at 175 px. Resized copies would save about 109 KiB.

3 images (237 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

1 image further down the page (28 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.41 g of CO₂e: 49.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

19 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Some lists contain elements other than list items, which screen readers announce wrongly.

Some list items are not inside a list.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is 170 characters; Google truncates after about 160, so the end of your pitch is cut.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 138 pages on vygon.com and 47 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://www.vygon.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://www.vygon.com/en/group-vygon/contribute-meaningful-mission-value-life has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 95 found) and read each the way a search engine does.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no form on the homepage, so every lead has to click through to another page first.

The homepage carries about 960 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 4 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
